change the GroupcompressBlock code a bit.
If the first decompress request is big enough, just decompress everything.
And when we do that, let go of the decompressobj.
After digging through the zlib code, it looks like 1 zlib stream object
contains a 5kB internal state, and another 4*64kB buffers. (about 260kB
of total state.)
That turns out to be quite a lot if you think about it.
In the case of branching a copy of 'bzr.dev' locally, this turned out
to be 383MB w/ bzr.dev and 345MB w/ only this patch. (So ~11% of peak).
Also, this was 'unreferenced' memory, because it is hidden in the
zlib internal state in working buffers. So it wasn't memory that Meliae
could find. \o/.
